Hello, i’m the IT manager for a medium sized company, we have a small office with a jurassic era security system.
The information i could find on the web is:
Brand: Testene Electronic
Year: Max 2002 (but could be older)
Model Nr.: Ts-C/4EPK
Problem: There’s a yellow light on the “INS DISINS” indicator.
I’ll leave a reference picture here:
Any help is extremely appreciated since i have no clue where else to search, thank you!
